Extending'from a point between the endsot the neck por-Y tion 12 and communicating with the discharge chamber 11 is a discharge port 13. This port 13 and as will be observed in the faucet A, the same is threads at its,

Figure 1 extends below the neck portion 12.

7 provided with an axially disposeddischarge opening'lS-andprovided at its inner end with ail-lat valve seat 19.

Thejdisch'arge means 13 embodies a stem which extends vertically through the body portion 10, and 'which stem is provided intermediate its ends with a crank portion 21 disposed in'axial relation to the'neck portion 12. The upper end o'l' the stem may be rotatably mounted axially of the cap 14, and outwardly of the cap a washer 22 may be provided for preventing longitudinal shifting of the stem within the faucet. is a lower stem portion 23 which extends into an upwardly opening socket 24 pro 'videdin a cylindrical shaped valve block 25.

This valve block 25 whichis adaptedfor positioning axially within the discharge chamber 11, has provided in its peripheral longitudinally extending face; diametric guideway's 26which are adapted to receive cap 1e preferably proand extending into the valve p the body portion of Extending below the crank 21' Threaded into the lower end of" the guides 16 for permitting of longitudinal movement of the valve block but preventing rotary movement thereof. Provided substantially midway of the. length of the valve block, and opening into the cylindrical socket 24, are diagonally extending guideways 27 arranged in oppositely extending relation to one another as illustrated in Figure 1. As will be observed in Figure 3,'thes'e' guidewa-ys'27 are arranged at diametrically opposite sides 01": the socket 2%. Extending through the lower stem portion 23, isa pin 28 which is adapted to travel in the guideways 27 upon rotation of the stem and which movement of the stem will causethc valve block to move upwardly or downwardly in accordance with the direction in which the stem is rotated. Suitable apertures 29 may be provided in the valve slot 'it'or permitting of the pin 28 being positioned in operative relation with the lower stem portion. A disc shaped gasket 30 is secured to the lower end of the valve slot 25' for seating flat upon the valve'seat 19 and closing the discharge opening 18 when'the discharge means is in a normal or olt position. A coil spring 31 coiled about the stem above the crank 21, has one end rigidly secured to the stem and its opposite end secured in the wall of the body portion 10 below the cap 14. An upwardly opening slot 32 may be provided in the body portion 10 for permitting of the outer end of the spring being slid into proper position during the assembling of the device. This spring 31 is adapted'to act upon the stem 20 for normally urging the crank portion 21 to a position away from the neck portion 12 as illustrated in Figure 1. t will be seen that when the crank 21 is in its normal position as in Figure 1, that the gasket 80 is in a position for closing the discharge opening 18.

Referring now to the measuring means C, the same embodies a tubular sleeve 35 preterably of an inside diameter equal to the inner diameter of the neck portion 12, and which sleeve has provided at its outer end an annular shoulder 36 against which the flange of a locking nut 37 engages when threaded upon the outer end of the neck portion 12 for coupling the neck portion in axial alignment with the sleeve. This sleeve is adapted to extend for a distance into the container G and be held in position as by suitable clamping nuts 38 disposed inwardly and outwardly of the 7 container. Provided adjacent the inner end of the sleeve, and inwardly of the container is a series of radially arranged inlet ports 39. Extending longitudinally and axially within the measuring chamber H formed by the neck 12 and sleeve 35, is a valve rod 40 provided with screw threads throughout its length, and having its forward end pivotally connected to one end of a link 41 extending into the faucet A. The opposite end of the link l-l is connected to the crank 21 so that when the stem 20 is manually rotated as by the handle as, a reciprocator motion will be imparted to the rod 40. hit ting upon the outer end of the valve rod 40 adjacent the body portion 10 of the faucet, and held against longitudinal shitting by the oppositely disposed jam nuts 43, is a'release piston valve 44 adapted to snugly engage the inner wall of the neck portion L 4 J I 12. Seiured upon the inner end or the rod 40 and held for movement therewith as by means of ain nuts 4:5, 1s an lnlet piston valve for opening and closing connnunication between the container E and chamber H.

chamber H has been closed by means of the Upon rotation of the stem inlet alve 46. 20 through 180, the valve as will be centered over the line are-0a,. thus closing the discharge port 13, while the valve 46 will be'centered ver the line YY, thus opening communication between the tank D and chan'iber H through the ports 39.

Threaded into the sleeve forwardly of the inlet ports 39, is a vent pipe l7communicating at its lower end with the chamber H and extending above the highest level of the liquid within the container D. This vent pipe 47, when the measuring means in a position for filling of the chamber H, allows for the air to readily escape from the chamber H when being filled. Since'during the filling operation of the chamber ll. the liqui in the container will rise to a like level in the vent pipe 47, it is desirable that the. valve 16 close the vent pipe when the valve is in its normal position as in Figure 1 so that the liquid in the vent pipe will be prevented from entering the chamber H when discharging into the faucet A. Such closing of the vent pipe l7 is desirable since the level of the liquid in the container will vary as the same is being drawn oil, and which would allow for varying amounts of the liquid tobe dispensed in accordance with the amount of liquid retained in the,

vent pipe when the chamber H is emptied into the chamber of the faucet. f desirable means may be provided for maintaining the liquid in the container 1'3 at a constant level, and in which case the valve 46 may move rearwardly of the ventpipe for affording t'reer movement of the liquid in the measuring chamber H, into the faucet. The vent opening 15 will allow for escapement of air within the body portion 10 and Lil igeenzev for occupying more or less area within the measuring chamber H: Binding'nuts 58 threaded upon the nod 40 at each end of the shell formed by the drums 50 and 51 are turned into binding engagement with the end walls of the drums for acting jam nuts to prevent relative movement of the drums when ad uSted. Thus it-will be seen that by so varying the external areaoi the telescoping drums 50 and 51, an elfec-' tive means has been provided for regulating the quantity of liquid which will enter the measuring chamber H.

In operation, it will be apparent that upon gripping of the handle 42 and rotating the same through 180 in ei'ther'direction, that the valve block 25 will be raised by reason of the pin 28 engaging the diagonally extending guideway 27, thus opening the discharge opening 18:and allowing the liquid in the discharge chamber 11 to readily flow from the faucet. rotation of the stem 20, the rod 10, through action of the crank 21 and link'dl, will be moved inwardly, the release piston valve closing the discharge port'13 and the inlet piston valve 1 6 moving'inwardly past the por s 39 thus allowing filling of'the chamber H with a predetermined amount'of the liquid from the container D. Upon releasing of the handle 42 the spring 31 acting upon the stem 20' will draw the valve rod 40 outwardly thus opening the discharge port 18 and closing communication between the tank D and vent pipe 47 as by the inlet piston valve 46. The valve block 25 atthis time has also been forced downwardly through action of the pin 28 and guideways 27, thus closing the discharge opening 18 and allowing the measured quantity of liquid in the chamber H to be emptied in the discharge chamber 11.

From the foregoing description .of the invention it will be apparent that a novel andeflicient automatic measuring valve has been provided whereby the ability to minutely regulate the quantity of liquid to be measured has been provided, and embody ing a novel arrangement whereby a measured quantity of the liquid is at all times ready to issue from the valve as soon as the same is manually operated.
